66However, when conducting such a review, the European Union judicature must not substitute its own economic assessment for that of the Commission (Case C-525/04 P Spain v Lenzing [2007] ECR I-9947, paragraph 57). The review by the European Union judicature of the complex economic assessments made by the Commission is necessarily limited and confined to verifying whether the rules on procedure and on the statement of reasons have been complied with, whether the facts have been accurately stated and whether there has been any manifest error of assessment or misuse of powers (see Joined Cases C-501/06 P, C-513/06 P, C-515/06 P and C-519/06 P GlaxoSmithKline Services and Others v Commission and Others [2009] ECR I-9291, paragraph 163).
